I wouldn't spend that much, even back when I was 18 (That would get you a Rolls then). For half your money you can get a very nice car that will last you 10-20 years if you keep up the regular maintenance. I never had to put my '98 Corolla in the shop, except for body repair when it got hit by a Modesto chick who couldn't see out the black tint on her windows and she drove into me on the freeway.
Go test drive a few cars; Hondas, Toyotas, or even a nice Yamaha motorcycle and get the one that gives you your money's worth. When I was 18 I could have bought a house and a couple of cars for $50k. Maybe $50k today is just chicken scratch.
I feel for you. Even if you're rich, money just doesn't get you much these days. Talk to a banker about investing.
I turned $35k into $200k following good advice of a banker.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
